Function fann_sys::fann_get_quickprop_mu

pub unsafe extern "C" fn fann_get_quickprop_mu(ann: *const fann) -> c_float

The mu factor is used to increase and decrease the step size during quickprop training. The mu factor should always be above 1, since it would otherwise decrease the step size when it was supposed to increase it.

The default mu factor is 1.75.
